“…The size of each single finger prototype was 200 × 10 × 5 mm 3 . First principle considerations and available literature data prompted us to start with 5 mm thick plastic scintillator planes, as thinner planes would not significantly increase the energy resolution, given the intrinsic proton range straggling of about 3-4 mm in our energy range [27].…”

This contribution describes the first results obtained within the iMPACT project, which aims to build a novel proton computed-tomography (pCT) scanner for protons of energy up to 230 MeV, as used in hadron therapy. The iMPACT pCT scanner will improve the current state-of-the-art in proton tracking at all levels: speed, spatial resolution, material budget, and cost. We will first describe the design of the iMPACT scanner, which is composed by a tracker and a range calorimeter. We will then illustrate the results of a test with the ALPIDE sensor, a monolithic active pixels sensor, developed by the ALICE collaboration, which will equip the iMPACT tracker in this first phase. We finally detail the characterization building elements of the prototype of the range calorimeter, which is composed of segmented scintillator fingers readout by SiPMs. Reported beam-test data will highlight how the technological choices we made well address the performances of a state-of-the-art pCT system.

“…The hodoscopic CsI calorimeter of the existing scanner [31] is both too slow and in need of tedious calibrations to ensure the needed uniformity [38]. A range counter with 4 mm scintillator plates with direct MCPP readout showed good SNR, with signals 3–5 times that of 3 mm plates and WLSF readout [39]. The baseline is a novel multi-stage scintillator (MSS) counter, consisting of three 10 × 10 × 40 cm 3 polystyrene blocks with light guides and 3″ photomultiplier (PM) readout [40].…”

“…Measured WEPL resolution for different degrader thickness for the WEPL detector choices: the existing CsI calorimeter [31], a range counter with 4 mm plates [39], one MSS block measured “head-on” labeled “calorimeter” [40], and a 3-stage MSS [40]. …”
